Today Martin is doing much better. He seems to be aware of the fact that his left hind leg is not working properly. What injury triggered this sudden semi paralyzed leg? My guess is a good as any so-called vet and/or Orthopedic doctor so it seems.
We decided to let nature take its course, giving the fact that endless tests does not benefit Martin nor our nerves. I honestly think that the only party benefiting from stressful (needless) tests are those whom decided to make a living of clueless pet owners.
